While Target is Halted and On Emulator Exit Options

This target option controls the processor's behavior when VisualDSP++
relinquishes DSP control (for example, when exiting VisualDSP++). The
options are detailed in
Table 2-4. While Target is Halted Options
Option Description
Stop I/O DMA Stops IO DMAs in emulator space. This option disables DMA requests when
the emulator has control of the DSP. Data in the EP, LINK, or SPORT DMA
buffers are held there unless the internal DMA request was already granted.
This option holds off incoming data and ceases outgoing data. Because
SPORT-receive data cannot be held off, it is lost, and the overrun bit is set. The
direct write buffer (internal memory write) and the EP pad buffer are allowed
to flush any remaining data to internal memory.
